Pharmaceutical combination for improving glycemic control as add-on therapy to basal insulin

ABSTRACT

The present invention refers to a pharmaceutical combination for use in glycemic control in diabetes type 2 patients.

Subject of the present invention is a pharmaceutical combination for use in glycemic control in diabetes type 2 patients, said combination—comprising (a) desPro³⁶ Exendin-4(1-39)-Lys₆-NH₂ (AVE0010, lixisenatide) or/and a pharmaceutically acceptable salt thereof, (b) a basal insulin or/and a pharmaceutically acceptable salt thereof, and (c) optionally metformin or/and a pharmaceutically acceptable salt thereof. A further subject of the present invention is a pharmaceutical combination for use in the prevention of hypoglycemia, said combination comprising (a) desPro³⁶Exendin-4(1-39)-Lys6-NH2 or/and a pharmaceutically acceptable salt thereof, (b) a basal insulin or/and a pharmaceutically acceptable salt thereof, and (c) optionally metformin or/and a pharmaceutically acceptable salt thereof. Another subject of the present invention is a pharmaceutical combination for use in inducing weight loss in diabetes type 2 patients or/and for preventing weight gain in diabetes type 2 patients, said combination comprising (a) desPro³⁶Exendin-4(1-39)-Lys6-NH2 or/and a pharmaceutically acceptable salt thereof, (b) a basal insulin or/and a pharmaceutically acceptable salt thereof, and (c) optionally metformin or/and a pharmaceutically acceptable salt thereof.

In a healthy person the release of insulin by the pancreas is strictly coupled to the concentration of blood glucose. An increased level of blood glucose, as appears after meals, is rapidly counterbalanced by a respective increase in insulin secretion. In fasting condition the plasma insulin level drops to a basal value which is sufficient to ensure the continuous supply of glucose to insulin-sensitive organs and tissues and to keep the hepatic glucose production at a low level at night.

In contrast to diabetes type 1, there is not a lack of insulin in diabetes type 2 but in many cases, particularly in progressive cases, the treatment with insulin is regarded as the most suitable therapy, if required in combination with orally administered anti-diabetic drugs.

An increased glucose level in the blood over several years without initial symptoms represents a significant health risk. It could clearly be shown by the large-scale DCCT study in the USA (The Diabetes Control and Complications Trial Research Group (1993) N. Engl. J. Med. 329, 977-986) that chronically increased levels of blood glucose are a main reason for the-development of diabetes complications. Examples for diabetes complications are micro and macrovascular damages that possibly manifest themselves in retinopathies, nephropathies or neuropathies and lead to blindness, renal-failure and the loss of extremities and are accompanied by an increased risk of cardiovascular diseases. It can thus be concluded that an improved therapy of diabetes primarily has to aim keeping blood glucose in the physiological range as closely as possible.

A particular risk exists for overweight patients suffering from diabetes type 2, e.g. patients with a body mass index (BMI)>30. In these patients the risks of diabetes overlap with the risks of overweight, leading e.g. to an increase of cardiovascular diseases compared to diabetes type 2 patients being of a normal weight. Thus, it is particularly necessary to treat diabetes in these patients while reducing the overweight.

Metformin is a biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus (diabetes mellitus type 2) not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. Metformin is usually administered orally. However, control diabetes mellitus type 2 in obese patients by metformin may be insufficient. Thus, in these patients, additional measures for controlling diabetes mellitus type 2 may be required. Insulin is a polypeptide having 51 amino acid residues. Insulin consists of the A chain having 21 amino acid residues, and the B chain having 30 amino acid residues. The chains are coupled by 2 disulfide bridges. Insulin formulations have been used for a long time for therapy of diabetes mellitus type 1 and 2. Recently, insulin derivatives and insulin analogues have been used.

The compound desPro³⁶Exendin-4(1-39)-Lys₆-NH2 (AVE0010, lixisenatide) is a derivative of Exendin-4. AVE0010 is disclosed as SEQ ID NO:93 in WO 01/04156:

Reduction means in particular that the plasma glucose concentration reaches normoglycemic values or at least approaches these values.

In the present invention, normoglycemic value-s are blood glucose concentrations of in particular 60-140 mg/dl (corresponding to 3,3 bis 7.8 mM/L). This range refers in particular to blood glucose concentrations under fasting conditions and postprandial conditions.

The subject to be treated may have a 2 hours postprandial plasma glucose concentration of at least 10 mmol/L, at least 12 mmol/L, or at least 14 mmol/L. These plasma glucose concentrations exceed normoglycemic concentrations.

The subject to be treated may have a glucose excursion of at least 2 mmol/L, at least 3 mmol/L, at least 4 mmol/L or at least 5 mmol/L. In the present invention, the glucose excursion is in particular the difference of the 2 hours postprandial plasma glucose concentration and the plasma glucose concentration 30 minutes prior to a meal test

“Postprandial” is a term that is well known to a person skilled in the art of diabetology. The term “postprandial” describes in particular the phase after a meal or/and exposure to glucose under experimental conditions. In a healthy person this phase is characterised by an increase and subsequent decrease in blood glucose concentration. The term “postprandial” or “postprandial phase” typically ends up to 2 h after a meal or/and exposure to glucose.

The subject to be treated as disclosed herein may have a fasting plasma glucose concentration of at least 8 mmol/L, at least 8.5 mmol/L or at least 9 mmol/L. These plasma glucose concentrations exceed normoglycemic concentrations.

EXAMPLE

The Example refers to a randomized, double-blind, placebo-controlled, 2-arm, parallel-group, multinational study assessing the efficacy and safety of lixisenatide in comparison to placebo as an add-on treatment to basal insulin in combination with or without metformin in patients with type 2 diabetes.

The Example refers to a randomized, double-blind, placebo-controlled, 2-arm, parallel-group, multinational study assessing the efficacy and safety of lixisenatide in comparison to Placebo as an add-on treatment to basal insulin in combination with or without metformin in patients with type 2 diabetes. The approximate minimum study duration per patient was 79 weeks (up to 3 weeks screening+24-week main treatment+variable extension+3 days follow-up). The study was conducted in 111 centers in 15 countries. The primary objective of the study was to assess the efficacy of lixisenatide on glycemic control in comparison to placebo in terms of HbA_(1c) reduction (absolute change) over a period of 24 weeks.

A total of 496 patients were randomized to one of the two treatment groups (329 in the lixisenatide group and 167 in the placebo group) and 495 randomized patients were exposed to the investigational product (IP). Demographics and baseline characteristics were generally similar across the treatment groups. Four patients (2 on lixisenatide and 2 on placebo) were excluded from the mITT population for efficacy analyses due to lack of post-baseline efficacy data. During the whole-study treatment period, 115 (35.0%) lixisenatide-treated patients prematurely discontinued the IP, while 52 (31.1%) placebo-treated patients discontinued the IP. For both treatment groups, the main reason for treatment discontinuation was “other reasons” (15.8% for lixisenatide versus 13.2% for placebo) followed by “adverse events” (11.2% for lixisenatide versus 7.2% for placebo).

Efficacy analyses are based on the 24-week treatment: The least squared (LS) mean changes from baseline to Week 24 in HbA_(1c) were −0.74% for the lixisenatide group and −0.38% for the placebo group (LS mean difference vs. placebo=−0.36%; p-value=0.0002). A total of 86 patients (28.3%) in the lixisenatide group achieved HbA_(1c)<7% at Week 24 compared to 19 patients (12.0%) in the placebo group, and 44 (14.5%) lixisenatide-treated patients had HBA_(1c)≤6.5% compared to 6 (3.8%) of placebo-treated patients. The HbA_(1c) responder analysis (HbA_(1c)≤6.5 or <7% at Week 24) using Cochran-Mantel-Haenszel (CMH) method showed a significant treatment difference versus placebo for lixisenatide group at Week 24 (p-value=0.0003 and p-value <0.0001, respectively).

Treatment with lixisenatide also improved post-prandial glycemic control as shown by the results for the 2-hour post-prandial plasma glucose (PPG) and glucose excursion assessment. A statistically significant improvement in PPG after a test meal was demonstrated in the lixisenatide group, compared with the placebo group with a LS mean difference of −3.81 mmol/L (p-value <0.0001). Furthermore, treatment with lixisenatide demonstrated a statistically significant improvement in the average of the 7-point self-monitored plasma glucose (SMPG) profile (LS mean difference of −0.88 mmol/L; p-value <0.0001) compared with the placebo group. For fasting plasma glucose, no statistically significant difference was observed between the treatment groups (LS mean difference versus placebo=−0.08 mmol/L; p-value=0.7579). Patients treated with lixisenatide showed a statistically significant decrease in body weight (LS mean difference of −1.28 kg; p-value <0.0001) compared with the placebo group without an adjustment for multiplicity. A total of 30 patients (12 [7.3%] in the placebo group and 18 [5.5%] in the lixisenatide group) received a rescue therapy. While achieving a better glycemic control, patients treated with lixisenatide also showed a statistically significant decrease in daily basal insulin dose compared to the placebo-treated patients. (LS mean difference of −3.69 U, p-value=0.0120).

Safety analyses are based on the whole study treatment: Lixisenatide was well tolerated. The proportions of the patients with treatment emergent adverse events (TEAEs) were generally comparable between the two treatment groups (87.5% in the lixisenatide group versus 85.6% in the placebo group). Two patients in the lixisenatide group and two patients in the placebo group had TEAEs leading to death. The number of patients with serious TEAEs was 46 (14.0%) in the lixisenatide group and 17 (10.2%) in the placebo group. One hundred thirty-eight (42.1%) lixisenatide-treated patients had symptomatic hypoglycemic events as defined in the protocol during the on-treatment period, whereas 65 (38.9%) patients inthe placebo group reported symptomatic hypoglycemia. Aside from hypoglycemia, the most frequently reported TEAE was nausea (29.3%) for the lixisenatide group and nasopharyngitis (12.6%) for the placebo group. Seven patients in the lixisenatide group (2.1%) and 1 patient in the placebo group (0.6%) experienced severe symptomatic hypoglycemia per the protocol definition. A total of 11 patients (8 [2.4%] lixisenatide-treated patients and 3 [1.8%] placebo-treated patients) reported 11 TEAEs adjudicated as an allergic reaction by the Allergic Reaction Assessment Committee (ARAC), and three of these events (2 events of anaphylactic reaction in the lixisenatide group and 1 angioedema in the placebo group) were adjudicated as possibly related to the IP. One lixisenatide-treated patient reported an event of pancreatitis, which was assessed as a recurrent pancreatitis and not related to the IP per the investigator.

1 Objectives

1.1 Primary Objective

The primary objective of this study was to assess the efficacy of lixisenatide on glycemic control in comparison to placebo as an add-on treatment to basal insulin in Type 2 Diabetes patients treated with basal insulin in terms of absolute HbAlc reduction over a period of 24 weeks.

1.2 Secondary Objective(s)

The secondary objectives of this study were:

To assess the effects of lixisenatide on:

-   -   Body weight, 2-hour postprandial plasma glucose after         standardized meal challenge test,     -   Percentage of patients reaching HbAlc<7%,     -   Percentage of patients reaching HbAlc≤6.5%,     -   Fasting Plasma Glucose (FPG),     -   Change in 7-point Self Monitored Plasma Glucose (SMPG) profiles,     -   Change in basal insulin and total insulin doses.

To assess lixisenatide safety and tolerability.

To assess lixisenatide PK.

To assess anti-lixisenatide antibody development.

2 Trial Design

This was a double-blind, randomized, placebo-controlled, 2-arm, parallel-group multinational study with an unbalanced 2:1 randomization ratio. The study was double-blind with regard to active and placebo treatments. The study drug volume (i.e., dose of active drug or matching placebo) was not blinded.

The patients were stratified by screening values of glycosylated hemoglobin A₁c (HbA₁c) (<8%, ≥8%) and metformin use at screening (Yes, No). After a screening period, patients were centrally randomized via interactive voice response system (IVRS) in a 2:1 ratio to either lixisenatide or placebo.

The approximate minimum study duration per patient was 79 weeks (up to 3 weeks screening+24 weeks main double-blind treatment+variable extension+3 days follow-up). Patients who completed the 24-week main double-blind period underwent a variable double-blind extension period, which ended for all patients approximately at the scheduled date of week 76 visit (V25) for the last randomized patient.

Patients who prematurely discontinued the IP were continued in the study up to the scheduled date of study completion. They were followed up according to the study procedures as specified in the protocol amendment (except 3-day safety post-treatment follow-up, pharmacokinetics assessment, and meal challenge test).

3 Primary and Key Secondary Endpoints

3.1 Primary Endpoint

The primary efficacy variable was the absolute change inHbA_(1e) from baseline to Week 24, which was defined as: HbA_(1c) at Week 24-HbA_(1c) at baseline.

If a patient discontinued the treatment prematurely or received rescue therapy during the main 24-week double-blind treatment period or did not have HbA_(1c) value at Week 24 visit, the last post-baseline HbA1c measurement during the main 24-week double-blind on-treatment period was used as HbA1c value at Week 24 (Last Observation Carried Forward [LOCF] procedure).

3.2 Secondary Endpoints

3.2.1 Efficacy Endpoints

For secondary efficacy variables, the same procedure for handling missing assessment/early discontinuation was applied as for the primary variable.

Continuous Variables

-   -   Change in 2-hour postprandial plasma glucose (mmol/L) after a         standardized meal from baseline to Week 24     -   Change in 7-point SMPG profiles (mmol/L) (ie, the average and         each time point of the 7 points) from baseline to Week 24;     -   Change in FPG (mmol/L) from baseline to Week 24     -   Change in body weight (kg) from baseline to Week 24     -   Change in glucose excursion (2-hour postprandial plasma         glucose-plasma glucose 30 minutes prior to the meal test before         study drug administration) (mmol/L) after standardized meal         challenge test from baseline to Week 24;     -   Change in daily basal insulin dose (U) and total insulin         dose (U) from baseline to Week 24.

Categorical Variables

-   -   Percentage of patients with HbA1c<7% at Week 24     -   Percentage of patients with HbA1c≤6.5% at Week 24     -   Percentage of patients requiring rescue therapy during the main         24-week double-blind treatment period     -   Percentage of patients with ≥5% weight loss (kg) from baseline         to Week 24

3.2.2 Safety Endpoints

The safety analysis was based on the reported TEAEs and other safety information including symptomatic hypoglycemia and severe symptomatic hypoglycemia, local tolerability at injection site, allergic events (as adjudicated by ARAC), suspected pancreatitis, increased calcitonin, vital signs, 12-lead ECG and laboratory tests.

Major cardiovascular events were also collected and sent for adjudication by a Cardiovascular Adjudication Committee (CAC). The adjudicated and confirmed events by CAC from this study and other lixisenatide phase 3 studies will be pooled as necessary for analyses and summarized in a separate report based on the statistical analysis plan for the overall cardiovascular assessment of lixisenatide. The KRM/CSR will not present the summary of the adjudicated and confirmed CV events from this study.

4 Sample Size Calculation Assumptions

The sample size/power calculations were performed based on the primary-variable, change from baseline to Week 24 in HbA1c.

Three hundred patients in the lixisenatide treatment and 150 in the placebo treatment arm were expected to provide a power of 96% (or 86%) to detect differences of 0.5% (or 0.4%) in the change from baseline to Week 24 in HbA_(1c) between lixisenatide and placebo, assuming the common standard deviation (SD) was 1.3% with a 2-sided test at the 5% significance level.

5 Statistical Methods

5.1 Analysis Populations

The mITT population consists of all patients who were randomized, received at least one dose of double-blind IP, and had both a baseline assessment and at least one post-baseline assessment of any prim.my or secondary efficacy variables, irrespective of compliance with the study protocol and procedures.

The safety population was defined as all randomized patients who took at least one dose of the double-blind IP.

5.2 Primary Efficacy Analysis

The primary efficacy variable (change in HbA_(1c) from baseline to Week 24) was analyzed using an analysis of covariance (ANCOVA) model with treatment, randomization strata of screening HbA1c (<8.0, ≥8.0%), randomization strata of metformin use at screening (Yes, No) and country as fixed effects and using the baseline value as a covariate. Difference between lixisenatide and placebo and two-sided 95% confidence interval as wells as p-value were estimated within the framework of ANCOVA.

The LOCF procedure was used by taking the last available post-baseline on-treatment HbA_(1c) measurement (before the initiation of the new medication in the event of rescue therapy) as the HbA₁c value at Week 24.

The primary analysis of the primary efficacy variable \Vas performed based on the mITT population and the measurements obtained during the main 24-week double-bind on-treatment period for efficacy variables. The main 24-week double-blind on-treatment period for efficacy variables except those from the meal challenge test, 7-point SMPG, basal insulin dose and total insulin was defined as the time from the first dose of the double-blind IP up to 3 days (except for FPG by central laboratory, which was up to 1 day) after the last dose of the double-blind IP injection on or before V12/Week 24 visit (or D169 if V12/Week 24 visit was missing), or up to the introduction of the rescue therapy, whichever was the earliest. The main 24-week double-blind on-treatment period for efficacy variables from the meal challenge test including 2-hour PPG and glucose excursion, 7-point SMPG, basal insulin dose and total insulin was defined as the time from the first dose of the double-blind IP up to the date of the last dose of the double-blind IP injection on or before V12/Week 24 visit (or D169 if V12/Week 24 visit was missing), or up to the introduction of the rescue therapy, whichever was the earliest.

5.3 Secondary Efficacy Analysis

Once the primary variable was statistically significant at α=0.05, the testing procedure was performed to test the following secondary efficacy variables by the following prioritized order. The tests stop as soon as an endpoint was found not statistically significant at α=0.05.

-   -   1. Change in 2-hourpostprandial plasma glucose (mmol/L) after a         standardized meal test from baseline to Week 24,     -   2. Change in the average of the 7-point SMPG from baseline to         Week 24,     -   3. Change in FPG (mmol/L) from baseline to Week 24,     -   4. Change in body weight (kg) from baseline to Week 24,     -   5. Percentage of patients requiring rescue therapy during the         main 24-week double-blind treatment period.

No multiplicity adjustment will be made on the other secondary efficacy variables, which are not mentioned above.

All continuous secondary efficacy variables at Week 24 as described in Section 3.2.1 were analyzed using the similar approach and ANCOVA model as described above for the primary analysis of the primary efficacy endpoint. The estimates of the treatment mean difference between lixisenatide and placebo and two-sided 95% confidence intervals were provided.

The following categorical secondary efficacy variables at Week 24 were analyzed using a Cochran-Mantel-Haenszel (CMH) method stratified on randomization strata (screening HbA_(1c) [<8.0, ≥8%] and metformin use at screening [Yes, No]):

-   -   Percentage of patients with HbA_(1c)<7.0% at Week 24,     -   Percentage of patients with HbA_(1c)≤6.5% at Week 24,     -   Percentage of patients requiring rescue therapy during the main         24-week double-blind treatment period.

Number and percentage of patients with >5% weight loss from baseline at Week 24 are presented by treatment groups.

All secondary endpoints at the end of treatment were only evaluated by descriptive statistics (mean, standard deviation, median and ranges provided in CSR).

5.4 Safety Analysis

The safety analyses were primarily based on the on-treatment period for the whole study. The on-treatment period for the whole study was defined as the time from the first dose of double-blind IP up to 3 days after the last dose of IP administration during the whole study period regardless of rescue status. The 3-day interval was chosen based on the half-life of the IP (approximately 5 times the half-life).

In addition, the safety analyses for the 24-week double-blind treatment period will be summarized in CSR.

The summary of safety results (descriptive statistics or frequency tables) is presented by treatment groups.

6 Results

6.1 Study Patients

6.1.1 Patient Accountability

The study was conducted in 111 centers in 15 countries (Brazil, Canada, Chile, Egypt, France, Germany, India, Italy, Korea, Mexico, Puerto Rico, Russian Federation, Turkey, United Kingdom and United States). A total of 879 patients were screened and 496 were randomized to one of the two treatment groups. The main reason for screening failure was HbA_(1c) value at the screening visit was out of the protocol defined range (205 [23.3%] out of 879 screened patients).

Of the 496 randomized patients, 495 were exposed to the IP. One patient from lixisenatide group was not exposed to the IP. Four patients (2 in the lixisenatide group and 2 in the placebo group) were excluded from mITT population for efficacy analyses due to lack of post-baseline efficacy data. Table 1 provides the number of patients included in each analysis population.

For the efficacy populations, patients are tabulated according to their randomized treatment (as randomized).

6.1.2 Study Disposition

Table 2 provides the summary of patient disposition for each treatment group. During the whole-study treatment period, 115 (35.0%) lixisenatide-treated patients prematurely discontinued the IP, while 52 (31.1%) placebo-treated patients discontinued the IP. For both treatment groups, the main reason for treatment discontinuation was “other reasons” (52 patients [15.8%] for lixisenatide and 22 patients [13.2%] for placebo), mostly being personal reasons such as moving out of town, lost job, family issues or too busy to commit to the visit schedules, followed by “adverse events” (37 patients [11.2%] including 2 non-TEAEs for lixisenatide versus 12 patients [7.2%] for placebo).

For the 24-week main treatment period, 53 (16.1%) patients in lixisenatide group and 20 (12.0%) in placebo prematurely discontinued the IP with the main reason being adverse events (26 patients, 7.9%) for lixisenatide group and “other” (8 patients, 4.8%) for placebo group. The time-to-onset of treatment discontinuation due to any reason for the overall treatment period is depicted in FIG. 2. A higher discontinuation rate was observed for the lixisenatide group.

6.1.3 Demographics and Baseline Characteristics

The demographic and patient baseline characteristics were generally similar between the two treatment groups for the safety population (Table 3). The median age of the study population was 58.0 years. The majority of the patients were Caucasian (77.6%). The lixisenatide group had more female patients in percentage (55.5% female and 44.5% male) than the placebo group (50.9% female and 49.1% male).

Disease characteristics including diabetic history were generally comparable between the two treatment groups (Table 4). One placebo-treated patient (#840608010) had Type 1 diabetes and was discontinued from the study shortly after the identification of the diagnosis.

The mean duration of basal insulin treatment for the study population was 3.11 years (Table 5). Majority of the patients took either long-acting insulin analogues (glargine 50.1%, detemir 8.7%) or NPH (40.0%) during screening and continued into the study treatment period with a few exceptions (1.6%) who took pre-mixed insulin instead. Eight patients (5 on lixisenatide and 3 on placebo) took pre-mixed insulin at screening and continued into the study. Two placebo-treated patients took two types of insulin (one on detemir+glargine and another on NPH+Novolin® 70/30 mix) during screening and continued into the study. All insulin usage including pre-mixed insulin is displayed in Table 5.

Three hundreds and ninety-two patients (79.2%) were on metformin at the screening visit with a similar usage proportion in the two treatment groups (lixisenatide 79.6% and placebo 78.4%, (Table 6). There were two discrepancies in the number of patients between “randomization strata of metformin use at screening” and actual “metformin use at screening” due to randomization strata errors.

6.1.4 Dosage and Duration

The average treatment exposure was 491.5 days (70.2 weeks) for the lixisenatide group and 510.4 days (72.9 weeks) for the placebo-group (Table 8). Of the 495 patients, 270 (82.3%) patients in the lixisenatide group and 146 (87.4%) patients in the placebo group received at least 169 days (24 weeks) of treatment; moreover, 171 (52.1%) patients in the lixisenatide group and 89 (53.3%) patients in the placebo group had at least 547 days (18 months) of treatment. Six patients (3 for lixisenatide and 3 for placebo) had a missing last administration date; of them, three were lost to follow-up (2 for lixisenatide and 1 for placebo) and hence their treatment durations were set to missing following the SAP data handling convention.

For the lixisenatide group, 286 (87.2%) patients were at the target total daily dose of 20 μg both at the end of the 24-week double-blind treatment period and at the end of whole double-blind treatment (Tables 9 and 10). For the placebo group, 161 (96.4%) patients and 162 (97.0%) patients were at the target total daily dose of 20 μg at the end of 24-week double-blind treatment period and at the end of whole double-blind treatment, respectively (Tables 9 and 10).

6.2 Efficacy

6.2.1 Primary Efficacy Endpoint

Main Analysis

Table 11 summarizes the results of the primary efficacy parameter, change from baseline to Week 24 (LOCF) in HbA_(1c) using an ANCOVA analysis.

The pre-specified primary analysis showed that treatment with lixisenatide resulted in a statistically significant decrease in HbA_(1c) from Baseline to Week 24, compared with the placebo group (LS mean difference versus the placebo group=−0.36%; p-value=0.0002).

The analysis included measurements obtained before the introduction of rescue medication and up to 3 days after the last dose of the double-blind investigational product injection on or before Visit 12 (Week 24), or Day 169 if Visit 12 (Week 24) is not available. Patients with both baseline and Week 24 (LOCF) measurements are included.

FIG. 3 illustrates the Mean (±SE) change from baseline in HbA_(1c) during the main 24-week double-blind treatment period. FIG. 8 in the appendix illustrates the Mean (±SE) change from baseline in HbA₁c over time up to Week 76. The HbA1c reduction was relatively maintained over time beyond 24 weeks.

Table 13 summarizes—the proportion of patients with treatment response in HbA_(1c)≤6.5% or <7% at Week 24, respectively. The analysis of HbA_(1c) responders using the CMH method showed a significant treatment difference versus placebo for the lixisenatide-treated group (p-value=0.0003 and p-value <0.0001, respectively) for both categories. At Week 24, 14.5% of lixisenatide-treated patients and 3.8% of placebo-treated patients had achieved HbA₁c values≤6.5%; 28.3% of patients in the lixisenatide group and 12.0% of patients in the placebo group had achieved HbA1c values<7%.

6.2.2 Secondary Efficacy Endpoints

Table 14-18, and Table 20-21 summarize the ANCOVA analyses of 2-hour post-prandial plasma glucose, average 7-point SMPG, FPG, body weight, basal insulin, and glucose excursion respectively. FIG. 4-7 illustrate the Mean (±SE) change from baseline in average 7-point SMPG, FPG, body weight, and basal insulin over time during the main 24 week double-blind treatment period. FIG. 9-13 in the apppendix illustrate the Mean (±SE) change from baseline in 2-hour post-prandial plasma glucose, average 7-point SMPG, FPG, body weight, and basal insulin over time up to Week 76.

The results of the 2-hour post-prandial plasma glucose after a test meal showed a statistically significant improvement from baseline to Week 24 in lixisenatide group compared with the placebo group (LS mean difference versus placebo=−3.81 mmol/L; p-value <0.0001). More over, treatment with lixisenatide substantially decreased post-prandial plasma glucose excursion from Baseline to Week 24 compared with the placebo group (LS mean difference=−3.80 mmol/L, 95% CI=−4.57 to −3.03) (Table 21).

For the average 7-point SMPG, a statistically significant improvement from baseline to Week 24 was observed in lixisenatide group compared with the placebo group (LS mean difference versus placebo=−0.88 mmol/L; p-value <0.0001) (Table 15).

Patients in both treatment groups showed a modest decrease in FPG from baseline to Week 24 (LSmean—0:63 for lixisenatide versus −0.55 for placebo) with no statistically significant difference observed between the lixisenatide and placebo group (LS mean difference versus placebo=−0.08 mmol/L; p-value=0.7579) (Table 16).

As per the testing strategy adjusting for multiplicity, inferential testing for body weight loss from baseline at Week 24 and the percentages of patients requiring rescue therapy at Week 24 were exploratory since the preceding test (FPG) failed to show statistically significant group difference.

The LS mean body weight loss from baseline to Week 24 was −1.80 kg for the lixisenatide-treated patients and −0.52 kg for the placebo-treated patients, with statistically significant difference observed between the two treatment groups (LS mean difference versus placebo=1.28 kg, p-value <0.0001) without an adjustment for multiplicity (Table 17). More lixisenatide-treated patients (132%) than placebo-treated patients (3.1%) had a weight loss of 5% or more from baseline to Week 24 (Table 18).

The percentages of patients requiring rescue therapy at Week 24 was slightly lower in the lixisenatide group than in the placebo group (18 patients [5.5%] in the lixisenatide group and 12 patients [7.3%] in the placebo group) (Table 19).

While achieving a greater HbA1C reduction, patients in lixisenatide group showed a steady reduction in daily basal insulin dose over the treatment period (FIG. 7) and reached a statistically significant decrease in mean change at the endpoint (Week 24) compared to the placebo group (LS mean difference versus placebo=−3.09 U; p-value=0.0412) (Table 20). The results from the analysis of the change in “total insulin dose” (not shown) are identical to those from the analysis on “basal insulin dose” due to the fact that the rescue insulin usage was excluded from the analysis.

6.3 Safety

An overview of the adverse events observed during the on-treatment period for the whole study is provided in Table 22. The proportions of the patients with treatment emergent adverse events (TEAEs) were generally comparable between the two treatment groups (87.5% for lixisenatide versus 85.6% for placebo). Four patients (2 in lixisenatide group and 2 in placebo) had TEAEs leading to death. The percentage of patients who experienced serious TEAEs was higher in the lixisenatide group (14.0%) than in the placebo group (10.2%). The percentage of patients with TEAEs leading to treatment discontinuation was 10.7% in the lixisenatide group compared with 7.2% in the placebo group. Tables 23, 24, and 25 summarize TEAEs leading to death, serious TEAEs, and TEAEs leading to treatment discontinuation by primary SOC, HLGT, HLT and PT, respectively. The most common TEAE leading to treatment discontinuation was nausea in the lixisenatide group (11 patients [3.4%]), while no patient in the placebo group discontinued the treatment due to nausea.

Table 35 in the appendix presents the incidences of TEAEs occurring in at least 1% of patients in any treatment group during the on-treatment period for the whole study. Hypoglycaemia was the most frequently reported TEAE for both the lixisenatide (138 [42.1%]) and placebo groups (68 [40.7%]). Aside from hypoglycemia, the most common TEAE in the lixisenatide group was nausea (96 patients [29.3%] for lixisenatide versus 16 patients [9.6%] for placebo) followed by headache (41 patients [12.5%] for lixisenatide versus 17 [10.2%] for placebo) and diarrhoea (37 patients [11.3%] for lixisenatide versus 10 [6.0%] for placebo).

According to the protocol definition for symptomatic hypoglycemia, 138 (42.1%) lixisenatide-treated patients and 65 (38.9%) placebo-treated patients reported at least one symptomatic hypoglycemic event during the on-treatment period for the whole study (Table 26). Of these patients having the symptomatic hypoglycemia events per protocol definition, 4 lixisenatide-treated patients had investigator reported AE terms other than hypoglycemia (hypoglycaemic unconsciousness, hypoglycemia unawareness, blood glucose decreased, and tremor), which are not displayed as the hypoglycemia PT in the TEAE summary table (Table 35). Conversely, 7 patients (4 for lixisenatide and 3±or placebo) who reported hypoglycemia TEAEs are excluded from the protocol defined symptomatic hypoglycemia events in Table 26 because of either not fulfilling the hypoglycemia per protocol definition (the event glucose values 260 mg/dL) or missing relevant information for analysis (the complementary form was missing for one placebo-treated patient).

Seven (2.1%) lixisenatide-treated patients reported 8 severe symptomatic hypoglycemia events per protocol definition, whereas 1 (0.6%) placebo-treated patients reported 1 severe symptomatic hypoglycemia event during the same period (Table 27).

Eight patients (2.4%) from lixisenatide group and one patient (0.6%) from placebo group experienced injection site reaction AEs (Table 28). The injection site reaction AEs were identified by searching for the term “injection site” in either the investigator reported AE PTs or PTs from the ARAC diagnosis after the allergic reaction adjudication. None of the reactions were serious or severe in intensity, nor did these AEs lead to IP discontinuation.

A total of 33 cases were reported for 28 patients as suspected allergic events by investigators and sent to ARAC for adjudication during the on-treatment period for the whole study. Of these, 11 events from 11 patients (8 [2.4%] lixisenatide-treated patients and 3 [1.8%] placebo-treated patients) were adjudicated as allergic reactions by the ARAC, but only 3 events from 3 patients (two anaphylactic reaction events from lixisenatide group and one angioedema event from placebo group) were adjudicated as possibly related to the IP (Table 29).

Patient 840635031 (lixisenatide): A 52-year-old female patient with a medical history of dyslipidemia, asthma, allergic rhinitis, allergies to drug, food, pollen and dust, as well as urticaria and angioedema in the past, reported a mild injection site reactions with each dose since 8 Jun. 2009 (21 days on the IP). The patient complained of local and generalized itching, and swelling at the injection site with erythema. She also presented with hoarseness, change in pitch of voice, wheezing and chest tightness. The vital signs during a reaction (17-June-2009, 9:08) were: BP129/62 mmHg, HR 67 bpm. She was treated with oral Benadryl and recovered on 18 Jun. 2009. The IP was discontinued on 17 Jun. 2009. The causal assessment was related per the investigator. The allergic reaction was adjudicated as anaphylactic reaction and possibly related to the IP by the ARAC.

Patient 840635033 (lixisenatide): A 58-year-old female patient with a medical history of hypertension, dyslipidemia, asthma, allergic rhinitis and allergies to drug and house dust, as well as rash in the past, developed pruritus and urticaria of severe intensity on 19 Jul. 2009 (25 days on the IP) following administration with the IP and oral metoclopramide, (newly started on 19-July-2009 and stopped on 20 Jul. 2009). The patient complained of generalized itching, flushing, swelling in lips, eyes and face, nasal congestion and feeling nausea. The vital signs during a reaction (23 Jul. 2009, 10:10) were: BP134/66 mmHg, HR 95 bpm. She was treated with oral Benadryl and rapidly improved. The IP was discontinued on 23 Jul. 2009. The causal assessment was related to the IP but also possibly to metoclopramide per the investigator. The allergic reaction was adjudicated as anaphylactic reaction and possibly related to the IP by the ARAC.

Per protocol, any increase in amylase and/or lipase above twice the upper limit of normal range (ULN) that had been confirmed by a repeat measurement was to be monitoredand documented on a pre-specified form: “adverse event form for suspected pancreatitis”. During the on-treatment period for the whole study, 6 (1.8%) lixisenatide-treated patients and 1 (0.6%) placebo-treated patient reported 7 TEAEs with the pre-specified AE form (Table 30). Among these 7 patients, one lixisenatide-treated patient (#840614004) had an AE ofpancreatitis.

Patient 840614004 (lixisenatide): A 60-year-old male patient with a medical history of prostatic hyperplasia, dislocated lumbar disc (L4), acid reflux, hypertension, depression, liver resection due to liver abscess and chronic smoking, was on insulin glargine, metformin and other concomitant medications including anti-hypertensive, antacids, and anti-inflammatory and pain medications.

On 5 Apr. 2010 (272 days on the IP), the patient was hospitalized for pancreatitis of severe intensity and the IP was discontinued. The patient complained of on-and-off recurrent diarrhea associated with nausea, vomiting and cramping epigastric pain for one week. The amylase was 166 IU/L and lipase was 40 U/L. His symptoms improved and he was discharged from the hospital on 8 Apr. 2010, but his lipase continued to increase. On 06-May-2010, the patient had a gastroenterology evaluation and a computed.tomography (CT) revealed dilatation of the pancreatic ducts, apparently due to chronic pancreatitis. On 24 Jun. 2010, 11 weeks—after the last dose of the IP, the patient developed severe exacerbation of pancreatitis and was hospitalized. The patient presented with acute abdominal pain with multiple episodes of vomiting. The patient's amylase level was 159 U/L and lipase was 1108 U/L. The patient recovered from the pancreatitis exacerbation on 27 Jun. 2010 and the causal assessment was not related to the IP per the investigator.

Patients who had at least one value of lipase or amylase3 ULN during the on-treatment period are summarized in Table 31. Ten patients (7 [2.2%] patients in the lixisenatide group and 3 [1.8%] in the placebo group) with elevated lipase (≥3ULN) were observed. One patient in the lixisenatide group had elevated amylase (≥3ULN), and none did in the placebo group.

Note: The number (n) represents the subset of the total number of patients who met the criterion in question at least once. The denominator (/N1) for each parameter within a treatment group is the number of patients for the treatment group who had that parameter assessed post-baseline by baseline PCSA status. Only the worsening of the worst case for each patient is presented by baseline status.

Per protocol, any calcitonin value≥20 μg/mL confirmed by a repeat measurement was to be monitored and reported on the pre-specified adverse event form for “increased calcitonin ≥20 μg/mL”. During the on-treatment period for whole study, 5 patients (4 [1.2%] for lixisenatide and 1 [0.6%] for placebo) reported 5 TEAEs of blood calcitonin increase (Table 32). Of these 5 patients, 1 lixisenatide-treated patient (#840636032) had calcitonin values 250 ng/L and 4 others had calcitonin values≥20 ng/L but <50 ng/L. In addition, one placebo-treated patient had a TEAE of “blood calcitonin increased” reported by the investigator (Table 35) although the values were <20 ng/L. This AE was not documented in the pre-specified AE form per protocol and therefore is not included in Table 32. A description of the case with calcitonin value≥50 ng/L is provided below:

Patient 840636032 (lixisenatide): A 55-year-old male patient with a medical history of depression, dyslipidemia and hypertension was on insulin glargine, metformin and other concomitant medications including multivitamins, gemfibrozil, valsartan, bupropion, fluoxetine and methylphenidate. On 24 Sep. 2009 (Week 24), an AE of “blood calcitonin increased” was reported for a value of 47.5 ng/L, which was the result of the first calcitonin measurement for this patient. The AE was not accompanied with any symptoms. Calcitonin rose to 75.9 and 70.7 ng/L in January and February, 2010 so the IP was discontinued. On 23-Feb-2010, the patient saw a thyroid specialist and underwent a thyroid ultrasound scan, which revealed a “normal” result. The follow-up calcitonin (27 May 2010) was 50 ng/L. A repeat thyroid ultrasound (28-July-2010) was again “normal”. The thyroid specialist assessed the event as “an incidentally discovered elevation in calcitonin level is of unknown significance” and recommended serial monitoring of calcitonin through time and a repeat ultrasound in one year. The causal relationship was not related to the IP per the investigator. A post-study calcitonin on 23 Dec. 2010 was 60 μg/mL (local laboratory reference <11 μg/mL).

Patients with at least one serum calcitonin measured during the on-treatment period of the whole study are summarized in Table 33 according to the 4 categories of calcitonin level at baseline. Eight (2.8%) patients inthe lixisenatide group and 1 (0.7%) patient in the placebo group had calcitonin values≥20 ng/L (Table 33) including those 5 patients (4 on lixisenatide) who reported a TEAE with the pre-specified AE form (Table 32). Four out of the 8 lixisenatide-treated patients with a calcitonin value≥20 ng/L (Table 33) did not report a TEAE with the pre-specified AE form because of an unconfirmed elevation; 2 had a single value≥50 ng/L (all other measurements <20 ng/L) and 2 had a value between ≥20-<50 ng/L. It should be pointed out that calcitonin measurement was introduced into the protocol via a protocol amendment after most patients had been randomized. Therefore, baseline values are missing for the majority of the patients (209 [88.2%] for lixisenatide and 101 [88.6%] for placebo).

On-treatment period for the whole study = the time from the first dose of double-blind study medication up to 3 days after the last dose administration. *Regardless of baseline. Note: The numerator represents the number of patients who were in the pre-specified categories in each baseline category. The denominator for each parameter within a treatment group is the number of patients for the treatment group who had that parameter assessed post-baseline by baseline status. A patient is counted only in the worst category.
